ath9k: fix ar5416Addac_9100 values

Writing the register at offset 0x98c4 causes a deadlock on the AR913x
SoCs. Although i don't have detailed knowledge about these registers,
but if i change the register offset according to the 'ar5416Addac' table,
it works. Additionally there is no reference to the 0x98c4 elsewhere.
